How much nitrous for a stock piston?

some great advice your giving him joe!
I will add that dynotune makes a great bottle heater for only 99 bucks, and that a purge kit is a good idea too...some like to purge through the motor, but i think its better to do it with the line...just make sure you dont put on a huge purge show so that the bottles start dropping in nitrous and pressure like crazy- thats gay lol....cold fusion makes a nice and affordable purge kit, might wanna check out before going to a NOS or NX brand solenoid (there all from the same company anyways the noids)

I picked up a used NX system for 200.00 last month from a guy close to me, it has the big noids (checked them & there good), bottle, lines & nozzle for EFI, i'm looking at a plate kit from (yeah i know) Procomp for 59.95, it has a 40 hole spray bar, bottle brackets (which i need), 8 jets, braided fuel line & fittings, i'm alittle leary because its from Procomp, but maybe its not so bad.

Thanks for the heads up on the other stuff, i'll look into it, because NX heaters are 200.00.
